FIELD OF THE INVENTION

The present invention relates to azaindole derivatives which areinhibitors of ERK kinases (ERK1 and ERK2), to the process for thepreparation thereof and to the therapeutic use thereof.

BACKGROUND OF THE INVENTION

ERK protein belongs to the RAS/RAF/MEK/ERK pathway which plays a majorrole in cell cycle, proliferation, growth and survival. RAS/RAF/MEK/ERKpathway is activated by growth factors through their receptor tyrosinekinase that allows activation of GTPases RAS. In its turn, RAS activatesRAF proteins. Then, RAF activates MEK, which activates ERK. Finally,this enables phosphorylation of many substrates that have key roles inmetabolism, protein synthesis, cell proliferation and survival. RAFmutations lead specifically to an over-activation of thisRAS/RAF/MEK/ERK pathway and are responsible for 7% of all human cancers(Davies et al., Nature. 2002; Garnett et al., Cancer Cell. 2004).Indeed, RAF mutations are frequently observed in melanomas (27-70%),thyroid cancers (36-53%), colorectal cancers (5-22%) and ovarian cancers(30%). Likewise, RAS mutations occur in almost 30% of cancers and arepresent in pancreatic (90%), lung (35%), colorectal (45%) and liver(30%) cancers (Downward, Nat Rev Cancer. 2003). Thus, proteins ofRAS/RAF/MEK/ERK pathway represent targets of interest for cancerstreatment. Indeed, pharmaceutical companies focused on upstream kinases(RAF, MEK). However, resistances ultimately appear after currenttreatment with RAF and MEK inhibitors (Lito et al., Nat Med. 2013; Cauntet al., Nat Rev Cancer. 2015). Moreover, most resistances to MEK or RAFinhibitors induce ERK reactivation, through different mechanisms such asMEK mutation, B-RAF amplification, C-RAF mutation . . . (Little et al.,Oncogene. 2013). Furthermore, RAF or MEK inhibition suppresses ERKnegative feedback that restores upward signaling and finally ERKactivity (Lito et al., Nat Med. 2013). In light of the resistancephenomena that emerged after current treatment with RAF and MEKinhibitors, it is essential to develop new therapeutic options.

Except for its key role in hyperproliferative diseases, ERK signalinghas also been described as implied in neurodegenerative disorders suchas in Parkinson's, Alzheimer's and Huntington's diseases (Cheung et al.,Sci STKE. 2004; Bodai et al., Bioessays. 2012) and in inflammation suchas in the pathogenesis of Rheumatoid Arthritis (Thalhamer et al.,Rheumatology. 2008).

Thus, the present invention relates to ERK inhibitors development totreat a broad spectrum of diseases.

Some ERK inhibitors are already described in the prior art. Thus, U.S.Pat. No. 8,697,697 B2 describes substituted pyrazole derivatives asinhibitors of ERK2 kinase activity.

Pyrrolo[2,3-b]pyrazine derivatives are also reported as ERK inhibitorsin an international patent application WO 2014/060395 A1.

However, there remains a need for efficient compounds that are able toselectively inhibit ERK1 and/or ERK2 kinases.

The present invention is precisely directed to novel compounds for useas inhibitors of the ERK kinases activity.

The compounds of the present invention are novel azaindole derivativeswith at least an enhanced anti-proliferative activity.

The compounds according to the invention are also characterized by theirlow toxicity.

or one of their pharmaceutically acceptable salts.

After extensive searching of the ERK crystalline structure andstructural screening tests, the inventors have identified that theseazaindole derivatives of formula (I) selectively target the active sitesof the ERK kinases, and act as effective inhibitors of ERK kinasesactivity as demonstrated in the following examples.

In the meaning of the present invention, a “kinase inhibitor” isintended to mean a compound that reduces or suppresses the activity ofthe targeted kinase, as compared with said activity determined withoutsaid inhibitor.

Within the meaning of the invention, the term “prevent” or “prevention”with respect to an event is intended to mean the decrease of a risk ofoccurrence of said event.

-   -   a) Iodinating said 5-bromo-7-azaindole for obtaining a        5-bromo-3-iodo-7-azaindole,    -   b) Protecting the nitrogen atom of the pyrrolyl moiety of the        azaindole,    -   c) carrying out a first Suzuki coupling reaction of the compound        obtained at step b) with a 2-oxo-1,2-dihydropyridin-4-ylboronic        acid or ester derivative at a temperature within the range from        50 to 100° C. preferably from 70° C. to 80° C.;    -   d) carrying out a second Suzuki coupling reaction of the        compound obtained at step c) with an aryl or heteroarylboronic        acid under microwave irradiation at a temperature within the        range from 120 to 180° C., preferably 150° C.

Specifically, in accordance with the invention, the compounds of generalformula (I) can be prepared according to the process illustrated by thegeneral scheme 1 and 2, below:

5-Bromo-3-iodo-7-azaindole V is obtained from compound IV by iodinationwith N-iodosuccinimide (NIS) (step i). Iodination is performed in asolvent as acetone or THF, at room temperature. Compound V is thenprotected with a tosyl group in step ii, and the obtained compound VI isintroduced in a Suzuki coupling in step iii. The coupling is performedat 70-80° C., in presence of a 2-oxo-1,2-dihydropyridin-4-ylboronic acidor ester derivative and a catalytic amount of palladium, in a solvent asa mixture of acetonitrile and aqueous Na₂CO₃. Compounds of formula VIIare commercially available or prepared by a N-alkylation, starting from4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2(1H)-one, analkyl bromide and a base (as Cs₂CO₃ or Na₂CO₃) in anhydrous DMF. Suzukicoupling gives protected compound of formula VIII which is introduced asecond time in a Suzuki coupling, but this time under microwavesirradiation at 150° C., in presence of aryl or heteroarylboronic acid, acatalytic amount of palladium in a mixture of acetonitrile and aqueousNa₂CO₃ (step iv). Aryl or heteroarylboronic acids used in this step arecommercially available. Protecting group is also removed during thisstep, to give final expected compounds of formula IX.

The present invention also concerns a process for preparing compounds ofgeneral formula (I) wherein A represents 4- to 7-membered heterocyclicgroup, substituted or non-substituted, L and B being as defined in thepresent text, wherein the following steps are carried out in that order,starting from a 5-bromo-7-azaindole:

-   -   a) carrying out a Buchwald-Hartwig coupling with a compound        comprising a 4- to 7-membered heterocyclic group on said        5-bromo-7-azaindole for obtaining a 5-substituted 7-azaindole,    -   b) iodinating the 5-substituted 7-azaindole for obtaining a        5-substituted-3-iodo-7-azaindole,    -   c) protecting the nitrogen atom of the pyrrolyl moiety of the        azaindole,    -   d) carrying out a Suzuki coupling reaction of the compound        obtained at step b) with a 2-oxo-1,2-dihydropyridin-4-ylboronic        acid or ester derivative at a temperature within the range from        50 to 100° C. preferably from 70° C. to 80° C.,    -   e) optionally performing a microwave irradiation at a        temperature within the range from 120 to 180° C., preferably        150° C.

Examples of formula XIII can be prepared according to scheme 2.Synthesis starts from 5-bromo-7-azaindole IV which is substituted with asaturated 5- or 6-membered heterocycle via a Buchwald-Hartwig coupling(step v). Reaction occurs at 60° C. in presence of RuPhos Pd 2^(nd)generation, its ligand RuPhos and LiHMDS to give derivatives of formulaX.

In some cases, most frequently when the saturated heterocycle tointroduce presents several free H bonds, the substrate IV need first tobe protected with a 2-trimethylsilylethoxymethyl protecting group (stepvi). This group will permit the Buchwald-Hartwig reaction to occur withthe heterocycle, a catalytic amount of Pd(dba)₂, xantphos and sodiumtert-butoxide in toluene at 110° C. (step vii). Protecting group is thenremoved with ethylenediamine and TBAF in step viii to give intermediatesof formula X.

Synthesis continues by a iodination with NIS (as step i in scheme 1),followed by a protection with TsCl (as step ii in scheme 1), and then aSuzuki reaction to introduce a substituted 2-oxo-1,2-dihydropyridin-4-ylmoiety. This last step is performed at 70° C. during 1 to 2 h (as stepiii in scheme 1) and then during a few minutes e.g from 5 to 15 minutesat 150° C. under microwaves irradiation to directly obtained unprotectedcompounds of formula XIII.

Example 45: ERK2 Enzymatic Assay

To assess compounds capacity to inhibit ERK2 enzymatic activity, Z′-Lytebiochemical assay from Life technologies was used according tomanufacturer's instructions. Briefly, black 384-well plates containing100 nl of 100× compound solution in 100% DMSO, 2.4 μl kinase buffer, 5μl 2×MAPK1 (ERK2)/Ser/Thr 03 mixture and 2.5 μl 4×ATP solution wereused. Plates were shaken for 30 seconds and incubated for 60 minutes atroom temperature. Then, 5 μl of a 1:1024 dilution of Development ReagentA was added. Plates were shaken for 30 seconds and incubated for 60minutes at room temperature. A plate reader was used to readfluorescence. In this assay, ERK2 enzyme was used at a concentration of0.4 μg/ml (5.74 nM) at ATP Km (100 μM). Kinase buffer consisted of 50 mMHEPES pH 7.5, 0.01% BRIJ-35, 10 mM MgCl2, 1 mM EGTA. Compounds IC₅₀ weredetermined with a 3-fold serial dilution (10 point titrations induplicate).

ERK2 inhibitory activity of selected compounds (“ERK2 IC₅₀”) is reportedin table 2 as followed:

All tested compounds exhibit a capacity to inhibit ERK2 enzymaticactivity.

In particular, compounds having an activity designated as “A” providedan IC₅₀ value <10 nM. Compounds having an activity designated as “B”provided an IC₅₀ value between 10 nM and 25 nM. Compounds having anactivity designated as “C” provided an IC₅₀ value between 25 nM and 50nM. Compounds having an activity designated as “D” provided an IC₅₀value between 50 nM and 100 nM. Compounds having an activity designatedas “E” provided an IC₅₀ value >100 nM.

Example 46: Cell Line Proliferation Assay

A cell line assay was used to determine compounds capacity to inhibitcell proliferation. A375 cells (malignant melanoma) were grown to near80% confluence and seeded at 4000 cells per 100 μl per well in DMEM with10% FBS in 96-well flat bottom plates. Cells were incubated for 24 hoursat 37° C. under 5% CO₂. 100 μl compound solutions were added to cellsand incubated for 72 hours at 37° C. Total volume of media was 200 μlper well. Compounds were screened in 0.15% DMSO (final) using 6 pointtitrations in duplicate. Negative control wells consisted of vehicleonly (0.15% DMSO in 10% FBS DMEM). After 72 hours of compound treatment,SDS 1% (final) was added to positive control wells for 15 minutes at 37°C. Then, medium was discarded and replaced by 100 μl per well of a MTTsolution (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide)(Sigma, Cat #M5655) at 0.5 mg/ml in 10% FBS DMEM. Cells were incubatedfor 4 hours at 37° C. MTT reaction was stopped and homogenized by theaddition of 100 μl per well of SDS 10% 0.01M HCl. After 2 hours at 37°C., absorbance was measured at 570 nm in a Bio-Tek plate reader(PowerWave HT). Percent of proliferation inhibition was calculated usingnegative controls (0.15% DMSO) as 0% growth inhibition and positivecontrols (1% SDS) as 100% growth inhibition. IC₅₀ values (concentrationinducing a half-maximal growth inhibition) were determined by non-linearregression analysis of the inhibition curve generated by mean replicatevalues (using a sigmoid dose-response with variable Hill Slope andconstraining the top to a constant value of 100 and the bottom to avalue between 0 and 50). Analysis was performed using GraphPad Prismsoftware.
